Publication number: 20150217940Abstract: The present invention is based upon the discovery that neodymium polybutadiene rubber can be built onto heavy duty conveyor belts as a carry cover layer to greatly improve the wear resistance of the belt. Such heavy duty conveyor belts are of particular value for utilization in the mining of iron ore, copper ore, coal, and other abrasive materials. These belts accordingly offer a longer service life, reduce mine down-time, reduce costs, and improve overall mine productivity without having an adverse effect on worker health or safety, and without detrimentally impacting the environment. The present invention more specifically discloses a conveyor belt which is comprised of a carry cover layer, a reinforcement layer which is situated below the carry cover layer, and a pulley cover layer which is situated below the reinforcement layer, wherein the carry cover layer is comprised of neodymium polybutadiene rubber.Type: ApplicationFiled: January 28, 2015Publication date: August 6, 2015Applicant: VEYANCE TECHNOLOGIES, INC.Inventors: Mayu Si, Heng-Huey Yang, Watudura Prabodha Upul Silva, Michael K.

Publication number: 20120090720Abstract: The present invention is based on the unexpected discovery that the fluid resistance of hoses can be greatly enhanced by adding a chlorinated paraffin to a chlorinated polyethylene elastomer or a chlorosulfonated polyethylene elastomer which is used as the tubular inner core layer of the hose. Hoses made using this approach offer the advantage of having improved resistance to modern automotive fluids, including power steering fluid, transmission fluid, and the like, without compromising flexural characteristics or burst strength. Accordingly, the hoses of this invention provide a longer service life and better reliability then hoses made utilizing conventional technology.Type: ApplicationFiled: October 19, 2010Publication date: April 19, 2012Applicant: VEYANCE TECHNOLOGIES, INC.Inventors: Thomas George Burrowes, Kenneth Allen Bates
